While Facebook has invalidated 90 million users' single sign-on access tokens following a mega-breach, researchers warn that most access token hijacking victims still lack any reliable "single sign-off" capabilities that will revoke attackers' access to hyper-connected web services and mobile apps.

CISOs and CIOs must ensure their organizations plan for worst-case scenarios, conducting frequent "dry runs" of disaster recovery plans, says Tonguc Yaman, CIO of SOMOS, a New York Community Care Network, who formerly served as deputy CIO of Bellevue Hospital.

A recent incident involving a chronic care management company spotlights how paying a ransom to recover decryption keys from ransomware attackers can put sensitive data at additional risk. Security experts offer insights on how to prepare for the many challenges posed by attacks.

The latest edition of the ISMG Security Report offers an update on how Russian bots and trolls are spreading misinformation on vaccines via social media - and the public health impact of the campaign. Plus: Tips on disaster recovery, internet of things security.

Does social media fuel toxic politics and racial tension? We're still in the early of days of understanding the long-term effects of social media on society, but the early signs aren't good.
